Celebrate Pi Day at the Science on March 14 through 17. Hands-on activities and demonstrations to celebrate all things round!

Circles, cylinders, and spheres are the main event at the Science Center on March 14-17 at Pi Day. Pi (π) represents the ratio between the circumference of a circle and the diameter. Pi can be used to make calculations for any round number.

Visit the Saint Louis Science Center this March and see pizzas go splat, learn how to estimate the contents of a jar and use pi to calculate the best pizza deal. With plenty of free activities, jokes, trivia and a pi-related stage show, Pi Day has something for everyone.

Pi Day activities will take place throughout the Science Center’s main building.
